The share of jobs that can be done from home has increased steadily from 14% in 1991 to 45% in 2021. At the same time, actual Working From Home (WFH) remained limited to less than one fifth of its full potential before the Covid-19 crisis and is still below it in 2021.

The growth of WFH is largely unrelated to the evolution of job tasks, implying that the main obstacles to WFH have not been technical constraints. Low-skilled employees in particular have jobs that have long been largely teleworkable but they were barely teleworking before the Covid-19 crisis and remained still below 50% of their full potential during it. This pattern is not explained by differences in workers' desire to telework. It implies that the well-known large inequality in access to WFH along the earnings distribution cannot be attributed only to feasibility constraints and is potentially inefficient.
